Depth of field.
“Depth of field is the amount of distance between the nearest and farthest objects that appear in acceptably sharp focus in a photograph. A preferred selection Depth of field (“DOF”) in a focused subject in an image can be quite subjective”
“A device that controls the amount of light admitted through an opening. In photography and digital photography, aperture is the unit of measurement that defines the size of the opening in the lens that can be adjusted to control the amount of light reaching the film or digital sensor.”
A large aperture lets in more light than a small aperture.
The image of the daisy is taken by using a large aperture, you can tell this because the whole image isn’t in focus.
We then went out to take our own images.
These are good examples of large aperture and small aperture. The first image was taken using a large aperture. Which was f2. The second image was then taken with a small aperture of f22. The depth of field is shown more clear in the first image as it shows the sharp focus in the middle of the image.
